AmberLite™ FPA40 Cl Ion Exchange Resin is a gel, strong base (Type I) anion exchange resin, supplied in the Cl-form. While the resin has a gel matrix, it also exhibits some of the physical stability characteristics of macroporous resins. These properties make it ideally suited to the reversible uptake of organic color bodies commonly found in sucrose syrups. AmberLite™ FPA40 Cl resin can be used to decolorize sugar solutions < 200 ICUMSA and it can also be used in bioprocessing applications including the capture and recovery of clavulanic acid and decolorization of antibiotics.

AmberLite™ FPA51 Ion Exchange Resin is a macroporous, weak base anion resin. It is designed for the deacidification and purification of liquid foods and beverages. It is specifically useful in the deacidification of fruit juices and the production of neutral beverage bases from both fruit and malted sources

DuPont™ AmberChrom™ CG161 chromatography resins are macroporous polymeric resins for reversed phase HPLC.  These crosslinked DVB resins have a mean pore diameter of 150 Å as measured by N₂ BET and are ideally suited for small peptides and oligonucleotides, as well as small molecule drugs. With high mechanical robustness and chemical resistance, these resins are excellent alternatives to reverse phase silica such as C18 silica.  AmberChrom™ CG161M is supplied in a slurry of 50% resin by volume in an 80/20 (v/v) mixture of water and ethanol.  Dry grade (DuPont™ AmberChrom™ CG161MD) is available upon request. 

The FilmTec Aqualast 1812-HR Residential Reverse Osmosis Element is engineered to provide exceptional anti-scaling performance and high rejection, crucial for water systems dealing with high Total Dissolved Solids (TDS) and hardness. This product integrates advanced anti-scaling flat sheet technology into an 1812 configuration, ensuring compatibility with standard housing elements. It is designed to enhance water efficiency significantly, holding promise for long service life even under high TDS conditions often found in high-recovery systems. The element boasts a reduction in water usage by up to 67% and can last up to twice as long in harsh water conditions compared to the previous generation. The membrane efficiently cuts down salt passage, including nitrates, by 40%. Certified by NSF and fabricated under the rigorous 6-sigma system, the product underscores its efficacy and reliability in domestic reverse osmosis systems.

The FilmTec Fortilife CR100 is a state-of-the-art fouling-resistant element designed to combat biological fouling in settings like wastewater treatment facilities. It features ultra-low differential pressure, ensuring optimal hydraulic balance and flux distribution across the system. Its advanced membrane chemistry offers notable resistance to organic fouling, promotes efficient cleanability, and supports low-energy operations with excellent solute rejection rates. Importantly, the CR100i variant includes iLEC interlocking end caps, enhancing productivity and reliability. The design of these membranes, with robust fouling resistance, can reduce cleaning frequency by up to 50% in environments prone to biological fouling. They are durable enough for cleaning across a broad pH range, from pH 1 to pH 13, ensuring long service life and cost-effective maintenance. Suitable for industrial and municipal wastewater reuse, they also support processes like demineralization of challenging feedwater in various industries.

DOW FILMTEC reverse osmosis (RO) membranes for home drinking water treatment units are some of the most reliable and consistent elements in the industry. Utilizing advanced membrane technology, the new DOW FILMTEC 500 GPD Element offers exceptional balance of flow and high rejection.

The DOW FILMTEC™ FORTILIFE™ CR100 element is one of the industry’s most advanced fouling resistant element technology specially designed to provide relief from biological fouling. The element’s ultra low differential pressure provides improved hydraulic balance (more even distribution of flux across all the elements in the system) in a biological fouling environment such as wastewater treatment. This product also boasts a reliable and durable membrane chemistry, providing organic fouling resistance, cleanability, low energy operation, and excellent solute rejection.

The DOW FILMTEC™ FORTILIFE™ XC70 Element offers the ability to achieve reject Total Dissolved Solids (TDS) level > 70,000 ppm within standard reverse osmosis (RO) operating limits, helping maximize the RO recovery rate. The element also provides improved fouling resistance and cleaning efficiency through careful module design and slower permeate flow rate decline enabled by a highly fouling-resistant membrane.

The DOW FILMTEC™ FORTILIFE™ XC80 Element offers users the ability to achieve reject Total Dissolved Solids (TDS) level > 80,000 ppm within standard reverse osmosis (RO) operating limits, helping lower brine volume and maximize water recovery in the brine concentration step. The element also provides improved cost-efficiency of the overall MLD or Zero Liquid Discharge (ZLD) system due to brine reduction to downstream thermal treatment, lower energy consumption and slower permeate flow rate decline enabled by a highly fouling-resistant membrane.

The DOW FILMTEC™ FORTILIFE™ XC-N Element allows industrial end users to reduce costly reverse osmosis (RO) concentrate waste by converting a large fraction of RO concentrate into pure, easier-to-crystallize salt solutions.
